Blurry Fractals

Beauty is the first test; there is no permanent place in the world for ugly mathematics (G. H. Hardy)

Newton basin fractals are the result of iterating Newton’s method to find roots of a polynomial over the complex plane. It maybe sound a bit complicated but is actually quite simple to understand. Those who would like to read some more about Newton basin fractals can visit this page.

This fractals are very easy to generate in R and produce very nice images. Making a small number of iterations, resulting images seems to be blurred when are represented with tile geometry in ggplot. Combined with palettes provided by RColorBrewer give rise to very interesting images. Here you have some examples:

Result for f(z)=z3-1 and palette equal to Set3:Result for f(z)=z4+z-1 and palette equal to Paired:Result for f(z)=z5+z3+z-1 and palette equal to Dark2:Here you have the code. If you generate nice pictures I will be very grateful if you send them to me:
